Her parents- She admires her dad and idolizes her mom. She loves spending time with them, especially making puns with them.Papyrus- She loves him (duh) and thinks he's funny. She likes training with him etc.

Alphys and Undyne- They're like her aunts. She likes watching anime with them and reading Alphys' fics, she also kinda dislikes her because she wrote toriel/asgore fics...

Asgore- She thinks it's her responsibility to get him a girlfriend, often setting him up with dates. She sees him as an uncle.

Asriel, Frisk and Chara- She admires all of them and loves hanging out with them and constantly seeks approval from them. She's as close with them as normal siblings.

Andy- - I mean, they're best "friends"
